Politician：Each year, small businesses create more jobs than do large established businesses. Therefore, in order to reduce unemployment in the long term, we should provide incentives for starting small businesses rather than for expanding established large businesses.

Which of the following, if true, casts the most doubt on the politician’s

argument？

In general, people employed by small businesses report higher job satisfaction than do people employed by large businesses.

Among the currently unemployed are many people with sufficient job skills to perform the jobs that small businesses would create.

Providing an effective incentive for starting a business generally costs significantly less than providing an effective incentive for expanding a large business.

A high proportion of small businesses fail within three years of starting because of their owners’ inexperience.

The average large business contributes more money to politicians campaign funds than the average small business does.
